All,

I just had the ole $1200 conversation with my MB dealer about replacing a malfunctioning Yaw Rate Sensor on my 2000 C230K. The problem is that this is causing a dangerous situation because it is randomly engaging my brakes at all speeds when it thinks the car is out of control.

My $1200 question is:

Can you simply remove the Yaw Rate Sensor? My assumption is in doing so the BAS/ESP system will default to "OFF" and stay disengaged. If this is the case I can live with the illuminated BAS/ESP light.

Anyone know?

 

what happens if you turn off the ESP with the ESP switch? does it help? are your tire sizes correct on the car?

 

Even with the ESP turned off the the problem persists. The problem is the yaw rate sensor. The tires and wheels are OEM. I am just wondering what would happen when the Yaw Rate Sensor is removed. Will the computer simply shut the ESP system down when it does its initial diagnostic that it goes through during the start up process.....if it does then its a very very simple and cheap solution...if not I may be getting rid of the car.

Thanks for your insight though!

 

Please let your ESP System read-out with Bosch KTS 650 or Star and tell as the Error- Code.

 

The codes are:
C1012
C1200
C1200-001
C1200-004
C1200-016
C1140-128
C1202

I think the problem is reduced down to the Yaw Rate Sensor....do you by chance know what would happen if i just remove the sensor and drive the car without it?

 

you can still drive it youll just have the esp light on. and your traction control wont work

 

AWESOME!!! That is great news because I really did not want to shell out 1K plus on this issue.

Even though the sensor is out and the Traction Control (BAS/ESP) is shut down, the ABS system will still operate normally right? I assume yes because it is an independent system, but just wanted to ask to be sure.

The Yaw Rate Sensor is in the trunk of the 2000 C230 right? Under the plastic screw down panel?

Thanks so much for your help!

 

It would be nice to know the Chassies No. and Engine No. so i can help you better.
All the Code's are not eraseble?Still caming back after ereasing them?

 

Here how to test the Yaw Sensor:1. Remove the Sensor from the Car.2. Aply 12 Volt on the Sensor.3.Connect on the output terminal the multitester. 4.Move the Sensor to the left and right. Wen the output voltage is changing up and down the Sensor is ok.Wen the voltage is zero or stable supply voltage the Sensor is damage.
Hope this will clarify the problem.

any update on what happened with you
because i'm having the same with my C240 2001 car
